The Hertz Tesla rental is also offered only in California. The Model S is available at Hertz locations in Los Angeles, Orange County, San Diego, and San Francisco.

Yet another option for drivers in California is MPG Car Rental--a rental company specializing in hybrid, diesel, and other green cars--which offers Tesla Model S rentals at its locations in Los Angeles and Venice, California.

MPG lists a rate of $499 a day for a Model S, including 100 miles per day with an additional $2.00 charge for each extra mile.

While the project is still being crowdfunded, it would theoretically work like other car-sharing services, with users coordinating rentals through smartphone apps, and never having to visit a rental office.

A quick perusal of Getaround's website netted a black Model S available for $25.00 an hour. That comes with 200-mile-per-day limit, (there's a $0.40 charge for each additional mile), and a request from the owner not to scuff the rims.
